rIhis invention relates to an improved construction of scissors and constitutes a division of my former copending application, filed September 16, 1937, Serial No. 164,260. i

It is a primary aim of this invention to pr vide an improved construction of scissors cognprising the combination of a novel construction of shear frame, a detachable holder for detachably connecting a razor blade to one of the jaws of the frame, and a second holder having-,an integral blade element for co-acting with :the razor blade to provide the cutting blades of the scissors.

A particular advantage of the invention resides in the fact that the blade holder may be readily detached from the razor blade to provide 'for ready replacing of Ithe razor blade lwhile lthe holder provided with the integral blade element may likewise be readily detachedfor sharpen'ng or replacing. K Another object of the invention is to provide a novel form of blade holder and supporting jaw to enable the blade holder to be readily detached and reversed so that the razor blade, carried thereby, may be employed as a knife. 'f4'.-

Other objects and advantages of the invention will hereinafter become more fully apparent from the following description of the drawing, which illustrates a preferred embodiment thereof, and wherein- Figure l is a side elevational view showing the scissors assembled and in a closed position,

Figure 2 is a similar view showing the razor blade holder reversed to position the razor 'blade for use as a knife, .-t.

Figure 3 is `a transverse sectional View taken substantially along the plane of the line 33 of Figure l, and f Figures 4 and 5 are perspective views of the razor blade holder and the cutter frame, respectively.

Referring more particularly to the drawing, wherein like reference characters designate like or corresponding pants throughout the different views, IiI designates generally the shear frame comprising a pair of jaws, designated generally II and I2 which are provided with integrally formed handles I3 and I4, respectively. 'I jhe jaws II and I2 are pivotally connected at I5 'adjacent the shank ends of the handles I3 and 1I4. Jaws II and I2 each include the integral portions I6 and Il which are disposed substantially; at right angles to each other. The portions Il are formed integral with the shank ends of the handles I3 and I4 at the pivot I5 and Iare disposed in alined oppositelyprojectng relationship when the jaws II and I2 are in a closed position so that the portions I6 are disposed in spaced apart, substantially parallel relationship.

The portions I6, as best seen inv Figure 3, are'v 5 polygonal shaped in cross section. A razor blade holder, designated generally I8, includes va head portion `.I 9 which is recessed -to receive the portion I6 of either of the jaws II or I2. As illustrated, the holder I8 is mounted on the jaw II. Holder .l'O I8 also includes a recessed clamping portion 20 for receiving the enlarged head 2! of asafety razor 'blade 22. The ends of the clamping yportion 2li, as seen in Figure 4, are open to-permit the razor.'blade 22 to be detached therefrom byll being moved longitudinally thereof. Clamping portion 2li is restricted at its bottom, at 23, to prevent lateral movement of the blade 22, in one direction relatively to the holder i8 while the portion IG, on which the holder I8 is mounted,;20

. prevents lateral movement of the blade 22 in the opposite direc-tion. The holder I8 is further provided with a reinforcing flange '24 which extends from one side of the clamping portion 20 Yand which engages 'against one side of the blade 22,25 Flange 24 terminates above the cutting edge 25 of the blade 22. l

A cutter frame 26 is provided with a recessed head 2l which is slidably mounted on the portion IB of the jaw I2. A blade element 23 extendsig() therefrom, inwardly of the portion i6. One side of the blade element 28 slidably eng-ages against the exposed side of the razor'bladefZZ. The free -edge of the blade element '2S is beveled on its opposite side to provide a cutting ledge 29 which35 is tapered toward the outer end of the frameA 2B which end and 'the corresponding portion of the head 2'! are beveled at 30. The opposite end of the blade element 28 is elongated and flared outwardly, .away .from the blade .22, to form a guider: 40 3l fora purpose which will hereinafter be described.

From the foregoing it will beseen, that the holder I8 and the cutter frame 25 are slidably mounted on the portions I6 of the jaws I I and 45 I2, respectively, so that either the holder or frame is readily detachable by being moved outwardly 'relatively to the jaws. When the shear frame I0 is in a closed position, as illustrated in Figures 1 and 3, the cutting edges of the blade 22 50 and cutting element 28 are in overlapping relationship. By opening the handles I3 and I4 portions II of the jaws II and I2 will be moved away from one another to move the cutting edges of the razor blade 22 and cutting element 28 out 55 of engagement with each other. As the jaws are again moved toward a closed position the inner end of the cutting edge 25 will engage the guide 3| by means of which it will be guided into proper engagement with the` element 28. Due to the taper of the cutting edge 29 and to the swinging movement of the portions4 I6, the cutting edges 25 and 29 will execute a shearing cut similar to the conventional scissors. 'I'he reinforcing flange 24 is provided to prevent the cutting edge of the razor blade 22, which is relatively flexible, from springing outwardly when contacting an article disposed between the cutting edges 25 and 29 and `to thereby maintain the cutting edges in engagement during the cutting stroke so that the proper shearing action will be obtained.

As heretofore mentioned, the razor blade 22 may be removed longitudinally from the holder I8 and replaced by a new blade when dull and the cutter frame 26 may be removed from its supporting portion I6 and replaced or sharpened lthus eliminating the necessity of sharpening the blades as is required in conventional scissors or shears.

The shears l may also be used as a knife by detaching the holder l 8, reversing it and reapplying it so that the razor blade 22 extends away from the jaws H and l2, as seen in Figure 2.

Various modifications and changes are contemplated .and may obviously be resorted to as only a preferred embodiment of the invention has been illustrated and described.

I claim as my invention:

1. A scissors comprising a shear frame including a pair of pivotally connected handle members, portions formed integral with and disposed at an angle to said handle members, said portions projecting in opposite directions to aline in one position, polygonal shaped Shanks :formed integral with said portions and projecting therefrom substantially at right angles thereto, said shanks being parallel when said portions are alined; a frame including a portion shaped to closely engage one of said Shanks, said frame portion terminating in spaced jaws for engaging the head of a safety razor blade and being provided with inturned portions for engaging beneath said head, one of said portions being elongated to engage against one side of the blade to provide reinforcing means therefor; a second frame having a portion shaped to closely engage the other shank, a blade element formed integral with said second frame and projecting from the shank engaging portion, the exposed side of said razor blade being positioned to slidably engage one side of said blade element, and said blade element having its free edge tapered toward its outer end and beveled on its opposite side to provide a cutting edge for co-acting with the razor blade.
